Hi, There are a few differences between GeForce and Quadro cards : Quadro support quad-buffering, which is usefull if you want to have stereo. The newer geforce cards may support it also due to the current buzz around stereo. There is also support of g-sync cards, which can be usefull on tiled-displays + stereo systems. We noticed some performance differences for wireframe representations : it seems that quadro are faster than geforce for this kind of representations (which is kind of logical since those representations are not often used in games...)

VTK/ParaView just make standard GL calls so you won't gain anything by using a similarly configured Quadro over a GeForce card. On the other hand, Quadro's tend to have faster GPUs and more memory. If you don't need lots of GPU memory, GeForce cards in general offer a pretty good cost/performance tradeoff.

Some sites say the Quadro is better for CAD applications but is this true for ParaView?

Get an EDID file of a display device and use that in the config file (see attached file xorg-forced-monitor-EDID.conf for an example). b. Use a modeline (see attached file xorg-forced-monitor-modeline.conf for an example). The config files use more options than necessary - but that's because they are auto-generated. For documentation on the options, refer to /usr/share/doc/NVIDIA_GLX-1.0/README.txt HTH -- Shree From: [email protected] [mailto:[email protected]] On Behalf Of Paul McIntosh Sent: Wednesday, September 01, 2010 4:16 AM To: 'Paul Edwards'; 'paraview' Subject: Re: [Paraview] Advice on graphics cards Hi Paul, I think you are stuck with eitther a Tesla or Quadro on a cluster. This is due to the ability to configure those cards to work without a display (see the release notes for the latest drivers though). I'd be interested to hear otherwise as we have a few GTX280 nodes that are currently just used for CUDA. Maybe there is a way to "spoof" a monitor another way?
